Product Description

The ABB AMC-DC (Part Number: 3ADT309900R1) is an Auxiliary Motor Control Board designed to enhance the capabilities of ABB’s DC drive converters. It is typically a plug-in or add-on board that extends the functionality of the main drive control unit (e.g., the SDCS-CON-x board).

Its primary functions involve dedicated control and monitoring tasks related to the DC motor itself, which can include:

• Field Excitation Control: Providing interfaces and logic for controlling the motor’s field current, which is critical for field weakening operations to achieve higher motor speeds above the base speed.

• Motor Feedback Interface: Handling specific types of motor speed or position feedback signals (e.g., specialized encoders or resolvers) that may not be supported by the main control board.

• Auxiliary Outputs/Inputs: Providing dedicated auxiliary digital and analog signals for interfacing with external motor protection and cooling equipment.

Product Parameters

Product Advantages

• Expanded Motor Control: Enables advanced DC motor control techniques, especially field weakening, which allows the DC motor to operate efficiently across a much wider speed range.

• Flexibility and Customization: Allows users to select and implement specific motor feedback devices or auxiliary functions without requiring a completely new, expensive drive control unit.

• Seamless Integration: Designed by ABB to integrate perfectly with the control architecture of the host DC drive, ensuring reliable communication and coordinated motor control.

• Legacy Support: Important for maintaining and servicing older, reliable ABB drive systems where this auxiliary function is essential.

Precautions

• Drive Compatibility: The AMC-DC is compatible only with specific ABB DC drive platforms (often older series like DCS500). Ensure the drive’s control unit supports this specific auxiliary board before installation.

• Firmware Requirements: The host drive’s control board often requires a specific firmware version to recognize and correctly utilize the functions provided by the AMC-DC board.

• Configuration: Proper configuration within the drive’s parameters (e.g., setting up field weakening limits, feedback types) is crucial for correct and safe motor operation. Incorrect settings can damage the motor.

• Wiring: Always refer to the specific drive manual for the correct wiring diagrams for connecting the motor’s auxiliary equipment (e.g., field supply, cooling fan) to the AMC-DC board.

Product Applications

The AMC-DC board is used in any heavy industrial application relying on ABB DC drives where expanded motor control, particularly high-speed operation, is necessary:

• Metal Processing: Used in rolling mills, coilers, and winders where precise tension control and wide speed ranges are required.

• Pulp and Paper: Controlling the speed of paper machine sections which often operate DC motors in field weakening mode.

• Extrusion and Plastics: Applications needing wide speed variation and accurate torque control for material processing.

• Cranes and Lifts: Providing auxiliary control for robust motor performance under various load conditions.
